Street\Strip 408..Boiling it all down

I'm using summit brand headers,i think they cost about $120 1 5/8 tubes and they fit great and even have decent ground clearance.The comp is around 10.5 the exhaust is 2 1/2 all the way out the back with dynomax ultra flo's.Tire size is only 245/60/15.Intakes edel air gap.This is a mostly street driven car so i imagine if i did a few things to it mid to high 11's wouldn't be much of a problem.
